T 0 all whom it may concern:

Be it known that we, ALFRED KLisTNE residing at Essen, .Germany, and KARL show the invention applied to guns with wheeled gun carriages. v I

Figure 1 is a side elevation of the foundation, i

Fig. 2 is the corresponding plan view,

Fig. 3 is a section on the line 33 of F sr Fig. 4 is a section on the line 4l4. of Fig. 1,

Fig. 5 is on a larger scale a section on the line 55 of Fig. 3,

Fig. 6 is a plan View of parts of the foundation,

Figs. 7 to 10 are vertical longitudinal sections or the inner ends of the parts shown in Fig. 6.

The body of the foundation consists of four parts (A, B, C, D), which are of rectangular cross section particularly Fig. 4) and are built up of plates and angle irons and riveted together and therefore constructed like box girders. These parts are intended to form a rigid cruciform body, which is let into the ground. Each of the parts A, B, C, D carries on the end, which is located inward when the foundation is put together, two lugs a a b 6 c 0 (Z (V, respectively (see particularly Figs. 7 to 10) which project beyond" the inner end of the parts A, B, C, D. One lug is attached to the cover plate and the other lug to the base plate of the box and either directly to the under or upper side of the base and cover plate (see Figs. 8 and 9) or by the aid of an intermediate piece (a, a, d d) to the upper or under side of these plates (see Figs. 7 and 10). In consequence of this arrangement these lugs can engage with each the? by their nner a d? n the mann r are at the same level or height. Eachof the lugs is provided at the end which pro-- jects beyond the partsA, B, D with a circular through aperture a a b b c 0 (Z (Z respectively (see Figs. v6 to 10.) Into" shown in Fig. when thezparts A, B, C,

the openings a are inserted sleeves E,'F,

. which are rigidly connected to the lugs.

These sleeves, the one of whichisconnected to-the lower lug (a and is closed at'the bottom, serve to receive a pin G (see Figs;

1 to 3 and 5), which is adapted to bear with a collar g -(see Fig. 3) against the upper edge of the sleeve F and can be connected thereto by a bayonet joint f f 9? (see Figs. and 5).. .A bolt J Yadapted to'be inserted in through aperturesin the. sleeve E and thezpin G after this bayonet joint has been connected up (see Figs. 1 and. 3), serves to prevent the pin G from being turned around in the sleeves E F.

When assembling the foundatiom'the part I -A is-first laid out andthen the part 113, nextthe part C and finally the part D placed up to the part A so that the parts form a cross and the lugs b 0 (Z engage with their apertures 12 0 (Z over the sleeve E and the lugs 19 c d with their openings 6 0 d over the sleeve F. The pin G is then inserted in the sleeves E F and locked to the sleeves by means of the bayonet joint f f g and the bolt J.

In'order to stiffen the parts A, B, C, D relatively to each other substantially chair nel shaped pieces a b 0 d (see Figs. 1, 2 and 6) are fixed to the side wall of these parts at right angles thereto and into them can be pushed struts H from above. struts H are I-shaped in cross section and are adapted to rest on the angle irons a b c (i which are attached to the pieces a b 0 (Z and carry pins and screws (see Fig. l) for the purpose of connecting them to the The struts H. These struts, which serve as a track for the wheels of the gun carriage and a roller m (see Figs. 1 and 2) the cover plates of the boxes B, C, D a short distance. In order to compensate this difference in height, that is to say, in order to provide a perfectly level track for the wheels of the gun carriage and the roller m plates a b c d are attached to the cover plates of the boxes A, B, C, D respectively.

The roller m is carried on a bearer M (see Figs. 1 and 2) for the trail of the gun carproject above Owing to its shape the foundation let into the ground has in addition to requiring a v comparatively small amount of construe tional material, great power of resistance, as the recoil of the gun no matter whether it takes place in the longitudinal direction of the supports of thefoundation or at an incline'to this direction, is transmitted by the high and long side walls of the carrier toa very considerable ground. area. The foundation therefore requires no anchoring by means of spikes, spades-or the like,

Claims.

'1, A foundation for guns comprising boxshaped. girders disposed in the shape of a cross, superposed lugs projecting from the inner ends of the girders and provided with registering apertures, alining sleeves passing through said apertures,v a pin adapted to pass througlrsaid alining sleeves to remov ably lock together the girders, I-shaped struts secured to the sides of said girders and disposed therebetween for bracing the same, said I-beams having their upper faces positioned so as to forma track surface substantially concentric with said locking pin.

2. A foundation for guns which comprises girders disposed in the form of a cross, said girders being box-shaped in cross sections,

means for detachably uniting said girders, and means d sposed between said girders and forming a track surface, for bracing the same and retaining them in their proper positions.

8.' A device of the class described which comprises girders arranged in the shape of a cross, superposed lugs secured to the inner ends of said girders, said lugs being provided with registering apertures, alining sleeves passing through said apertures and a pin: p'assing'through both sleeves and removably securedsin place, substantially as described.

a. A device of the class described which comprises girders disposed at right angles to one another in the shape of a cross, means for uniting the girders at their inner ends, a bracing means disposed'between the several girders which comprises channel-shaped pieces secured to the sides of the girders and struts which are I-shaped in cross section mounted in said channel-shaped pieces and having their upper face adjacent the top sides of'saidgirders, as and forthe purpose set forth.

The foregoing specification signed at 60 Essen, Germany, th1s 11th day of June, 1920.
